4.  Install the liner elbow and masonry adaptor on the lower end of the liner. 

5.  Move the fireplace forward enough to install the EXCEL chimney on the fireplace (elbow and length) then 

move the fireplace back into position as you connect the masonry adaptor to the EXCEL chimney. 

Using a New Masonry chimney 

Since the masonry chimney is not build yet, we recommend that you position your fireplace, install the EXCEL 
chimney on it and connect to the first length of liner before building the chimney as explained above and shown in 
Figure 12. The liner sections can easily be installed as the layers of brick are being placed. Since this is a new 
chimney, we recommend that you build it to the right size so you do not have to ovalize the liner but if you choose 
to use a 6"x10" clay liner you will need to ovalize the stainless steel liner to fit into the clay liner. 

Š

 REMEMBER:

 The stainless steel liner should be fitted 

inside the clay liner all the way to the top of the masonry 
chimney. It is not meant to replace the clay liner. 

FRAMING 

The enclosure walls can be framed with any suitable 
materials (2"x4" or 2"x6" studs, plywood, gypsum board, 
etc.). Because of the high heat output potential of the 
ORACLE2, combustible materials must NOT go closer to 
the fireplace than the standoffs, top, back and sides. 

You may also completely cover the top of a  ORACLE2 as 
long as you maintain all fireplace standoff clearances and 
the 2" clearances around the chased chimney. The 2" 
clearance around the chimney must be open from the 
fireplace up to the ceiling. See Figure 13 for an example 
of a close clearance installation. 

HEARTH EXTENSION 

The area immediately in front of the fireplace must be protected by a non-combustible material such as brick, tile, 
stone, or slate. Refer to Table 1 (G-H) for the depth and width the hearth protection should extend beyond the 
front and both sides of the door opening (see Figure 1). There is no minimum thickness required for the hearth 
extension. 

BENEATH HEARTH EXTENSION 

If the ORACLE2 is installed on a non-combustible floor, 
the spark guard specified below is not required. 

Install the spark guard provided (5" x 36" piece of sheet 
metal) halfway under the fireplace and halfway under 
the hearth extension and centered on the door opening. 
The spark guard will extend 2½" beneath the fireplace. 
This will make certain that sparks cannot lodge in this 
area and start a fire.  

If you are preparing a raised installation, you will need a 
custom made spark guard, either a "Z" shaped spark 
guard or a right angle spark guard (see Figure 14). The Z-shaped spark guard must be used if the height between 
the bottom of the fireplace and the top of the non-combustible flooring of the hearth extension is less than or 
equal to 2 ½". The height of the Z-shaped spark guard must equal the distance between the floor and the base of 
the unit and go under the hearth extension and the fireplace by at least 2½". If the unit is installed higher than 2 
½" from the top of the flooring, a right angle spark guard is necessary. The sides of the right angle spark guard 
should be at least 2½" x 2½" and must be covered with non-combustible material. Any custom-made spark guard 
must have the minimum width specified in Table 1 (I), and be installed centered on the door opening. 

Š

 NOTE

: Custom-made spark guards are not supplied.  

Always maintain 2" min.

clearance with chimney

Always respect the

fireplace standoffs

Leave the space between

the chimney and the

framing open (no firestop)
